Chiral active liquids

Active liquids are fluids of interacting particles individually powered by motors. In this talk, we focus on chiral active fluids that violate parity and time reversal symmetry. First, we show how to generate topologically protected sound waves in fluids of self-propelled particles flowing in active microfluidic devices. These chiral edge modes in classical active systems have properties similar to their electronic counterparts in quantum Hall fluids. Next, we discuss the collective behavior of interacting particles with active rotations but no self-propulsion (i.e., active spinning without walking) and the effect of compression on their phase behavior and hydrodynamics. Our results suggest robust design strategies for active metamaterials that bridge the gap between materials and machines and achieve functionalities not attainable in passive materials.

Applied Newton-Cartan Geometry

In this seminar I will give a non-specialist introduction into the non-relativistic version of Riemannian geometry, which is called Newton-Cartan geometry. The corresponding non-relativistic gravity theory, called Newton-Cartan gravity, has received a renewed attention due to unexpected applications as a new tool to examine the non-perturbative properties of non-relativistic quantum field theories. I will explain the basic construction of Newton-Cartan gravity plus some of its generalizations and applications. Location: 726 Broadway, 940, CCPP Seminar room

Phase Transitions and the Principle of Detailed Balance in Living Systems

The mechanics of cells and tissues are largely governed by scaffolds of filamentous proteins that make up the cytoskeleton, as well as extracellular matrices. Evidence is emerging that such networks can exhibit rich mechanical phase behavior. A classic example of a mechanical phase transition was identified by Maxwell for macroscopic engineering structures: networks of struts or springs exhibit a continuous, second-order phase transition at the isostatic point, where the number of constraints imposed by connectivity just equals the number of mechanical degrees of freedom. We will present recent theoretical predictions and experimental evidence for mechanical phase transitions in both synthetic and biopolymer networks. Living systems typically operate far from thermodynamic equilibrium, which affects both their dynamics and mechanical response. As a result of enzymatic activity at the molecular scale, living systems characteristically violate detailed balance, a fundamental principle of equilibrium statistical mechanics. We discuss violations of detailed balance at the meso-scale of whole cells.

The Other Bohr, Allostery and Biology’s Greatest Model

Only ten years after the discovery of the iconic structure of DNA, new questions were on biologist’s minds, namely, how are the macromolecules of the cell regulated so that they do what they are supposed to when and where they are needed. The initial resolution of the challenging question of biological regulation came in the form of the notion of “allostery”, an idea that its discoverer Jacques Monod himself referred to as "the second secret of life". We recently celebrated the 50th anniversary of the classic paper of Monod, Changeux and Jacob that introduced this far reaching idea. That important paper was followed shortly thereafter by a second one that revealed their musings on how simple statistical mechanical models can be used to capture how such allosteric transitions work mechanistically. In this talk, I will review the key features of the famed Monod-Wyman-Changeux (MWC) model and then describe its broad reach across many different domains of biology with special reference to the physics underlying how genes are turned on and off. One of the intriguing outcomes of this class of models is a beautiful and predictive scheme for collapsing data from entire libraries of mutants. Once we have considered some of the traditional uses of the MWC model, I will turn to more speculative recent ideas which use the MWC approach to consider the nature of kinetic proofreading.

Large-deviation statistics of the cosmic density field

In this talk, I will describe how a large deviation principle can be used to follow the gravitational evolution of the large scale structure into the mildly nonlinear regime. This approach allows for analytical predictions for counts-in-cells statistics that are beyond what is commonly achievable via other statistics such as correlation functions. The idea is to determine the mean cosmic densities within concentric spheres and study their joint statistics. This symmetry allows to use spherical collapse dynamics which leads to surprisingly accurate predictions where standard perturbative calculations usually break down. In particular, I will show results for the density and velocity statistics in concentric cells in comparison to state-of-the-art numerical simulations. Finally, I will discuss current efforts to extend the formalism to include primordial non-Gaussianity, bias and cylindrical cells and exploit its potential to constrain cosmology using future surveys.

Imaging the Surface States of a Strongly Correlated Topological Insulator

The prediction and subsequent discovery of robust spin-polarized surface states on topological band insulators has launched a new subfield of physics over the last decade. In the last few years it has been recognized that even more interesting, exotic, and potentially useful states of matter can arise when topology is combined with strong correlations. Strong correlations can lead to new topological classifications, fractionalized states, and many-body localization that preserves the topology of the insulating state against thermal destruction. The Hoffman lab has very recently achieved the first direct proof of a strongly correlated topological insulator. Using scanning tunneling microscopy to probe real and momentum space structure, our measurements on the heavy fermion material SmB6 reveal the evolution of the insulating gap arising from strong interactions. Within the narrow gap, we directly image a dispersing surface surface state that converges to a Dirac point close to the chemical potential. Our observations present the first opportunity to explore a strongly correlated topological state.

Radial Acceleration Relation in Rotationally Supported Galaxies

We report a correlation between the radial acceleration traced by rotation curves and that predicted by the observed distribution of baryons. The same relation is followed by 2693 points in 153 galaxies with very different morphologies, masses, sizes, and gas fractions. The correlation persists even when dark matter dominates. Consequently, the dark matter contribution is fully specified by that of the baryons. The observed scatter is small and largely dominated by observational uncertainties. This radial acceleration relation is tantamount to a natural law for rotating galaxies.
